What N245 means

The information about the patient's other insurance plan on the claim is incomplete or does not match the payer's records.

When a claim reports other coverage, the payer checks the other plan's name, ID, subscriber and relationship details. N245 means something in that other coverage section was missing or did not fit.

It adds detail to a coordination of benefits or missing information reason code, often 16 or 22.

Common causes

• The other payer's name or ID was left blank or entered incorrectly.
• The subscriber name, ID or birth date for the other policy does not match.
• The patient's other coverage ended, but the claim still lists it.

What to do next

1. Confirm the patient's current other coverage and the subscriber details.
2. Correct the other payer section on the claim and resubmit.
3. Update the patient's insurance file so the error does not repeat on later claims.
4. If the other coverage ended, ask the patient to update the payer's records too.
